Abstract: The present description discloses a public land mobile network (PLMN) selection method. The PLMN selection method comprises the steps of: running a first timer if a first request message has been transmitted multiple times to a first network node in a first PLMN, but a response message has not been received; selecting a second PLMN after the first timer has been started; and maintaining, without stopping, the first timer, which has been run for the first PLMN, even if a second request message has been sent to a second network node in the second PLMN, and an acceptance message for same has been received, wherein the retransmission, by reselecting the first PLMN, of the first request to the first network node in the first PLMN can be prevented until the first timer has expired.

Abstract translation: 本说明书公开了公共陆地移动网络（PLMN）选择方法。 PLMN选择方法包括以下步骤：如果第一请求消息已经被第一PLMN中的第一网络节点多次发送，但没有接收到响应消息，则运行第一定时器; 在第一定时器开始之后选择第二PLMN; 以及即使第二请求消息已被发送到第二PLMN中的第二网络节点，并且已经接收到针对第一PLMN的接受消息，并且不停止地维护已经为第一PLMN运行的第一定时器，其中， 可以防止通过重新选择第一PLMN向第一PLMN中的第一网络节点重新选择第一请求，直到第一定时器期满为止。

Abstract: A method performed by a terminal operating in a wireless communication system. Based on that the terminal is located in a non-allowed area, and based on the terminal having a pending uplink signaling to inform a change in a Packet Switch (PS) data off status of the terminal, the terminal transmits a service request message to a network node. The service request message includes service type information that is related to the change in the PS data off status of the terminal. The terminal then receives, from the network node, a response message to the service request message.

Abstract: Provided are a method and a device for processing network slice selection assistance information (NSSAI) rejected due to a network slice-specific authentication and authorization (NSSAA) failure. A user equipment (UE) receives a UE configuration update command message from an access and mobility management function (AMF). On the basis of failure of NSSAA with respect to single NSSAI (S-NSSAI0, the UE configuration update command message includes time information related to a timer. The UE adds the S-NSSAI to a rejected NSSAI, starts the timer on the basis of the time information, and deletes the S-NSSAI included in the rejected NSSAI after the timer expires.
